Five suspected migrants have been picked up from a small boat by French authorities off Audinghen in northern France.
A statement from the Prefecture Maritime de la Manche said a call for medical assistance raised the alert and a fishing vessel then found the group.
Two on board were suffering from hypothermia and all five were taken care of by emergency teams in France.
A rise in attempts to cross the Channel is being blamed on organised crime.
The vast majority of people trying to cross to Kent claim to be Iranian but the nationality of those rescued on Saturday is not yet known.
